Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: A bypass allowed WebSocket upgrade requests to completely skip authentication middleware, exposing internal interfaces to unauthorized actions.
Auth Bypass: The OAuth callback flow relied on client-side state parameters for authentication. Storing and verifying the session identifier in a secure, HttpOnly cookie is necessary to prevent authorization bypass.
Information Disclosure: Exposing the privileged Supabase service role key to the frontend due to a 'NEXT_PUBLIC_' prefix represents a critical risk of complete backend compromise.
